FAQ
Line Graph Generator questions
- How do I create a line graph online?
- Paste your data with time labels in the first column. The generator recognises years, months, quarters and ISO dates and switches to a line chart automatically.
- Can I plot multiple lines on one graph?
- Yes. Every additional numeric column becomes another line with its own colour and legend entry.
- Can I download the line graph as a vector file?
- Yes, export as SVG for infinite scaling in print or design tools, or as high-resolution PNG at 2x scale.
